Products Description
Gadolinium-doped ceria (GDC) can serve as an intermediate-temperature electrolyte for solid oxide fuel cells (SOFCs) under high-temperature conditions. Specifically, cerium(IV) oxide doped with 10 mol% gadolinium (GDC-10) is an electrolytic material featuring high oxygen-ion conductivity, enabling its operation at lower temperatures. This material can be synthesized through multiple approaches, including sol-gel methods, wet chemical processes, co-precipitation, hydrothermal techniques, and various combustion-based routes. For instance, gadolinium-doped ceria can be prepared via a cation complexation sol-gel technique. Compared to zirconia-based materials, GDC exhibits superior oxygen ion conductivity, making it a more favorable option for certain components in SOFC systems.
